The Minister of Petroleum and Natural Gas Hardeep Singh Puri on Thursday acknowledged that vehicles running on E20 petrol could witness a “minor” drop in fuel efficiency, according to a Times of India report, even as the government defended the nationwide rollout of ethanol-blended fuel and dismissed growing concerns over its impact on vehicle performance
The petroleum Minister admitted that mileage "may drop a little" with E20 fuel but argued that the trade-off was outweighed by better acceleration and improved engine performance. "Mileage, yes, it may drop a little, but mileage can drop a little because of various things," Puri said, as quoted by TOI, adding that ethanol-blended fuel improves acceleration and reduces engine knocking.
